Why Metabolic Health Matters
You can have a normal BMI and poor metabolic health, or live with obesity and have favourable metabolic markers. The number on the scale is only one part of how your body processes and stores energy.
If you’re finding weight management difficult despite consistent effort, one contributing factor may be insulin resistance — a metabolic condition that can make weight loss more challenging.
What Metabolic Health Means
Metabolic health reflects how well your body converts food to energy and maintains blood sugar, blood pressure and blood lipids. Poor metabolic health can increase the risk of conditions such as type 2 diabetes, cardiovascular disease and fatty liver disease. Early attention to these markers can help reduce health risks over time.
How Insulin Resistance Develops
Insulin is a hormone that helps glucose move from the bloodstream into cells for energy. With insulin resistance, cells become less responsive to insulin’s signal. The pancreas compensates by producing more insulin. Over time, this can lead to higher blood glucose levels.
Persistently elevated insulin can favour energy storage and make fat loss harder for some people. This is one reason standard advice can feel ineffective when insulin resistance is present.
Early Signs
Insulin resistance develops gradually. Possible signs include increased hunger or cravings, energy dips after meals, weight gain around the abdomen, rising blood pressure, changes in blood lipids (higher triglycerides and lower HDL), and, in some women, irregular periods or features of PCOS. Acanthosis nigricans (darker, velvety skin patches in body folds) can also be a sign.
Contributing Factors
- Genetics and family history
- Visceral (abdominal) adiposity
- Dietary patterns high in refined carbohydrates and added sugars
- Physical inactivity
- Poor sleep, chronic stress
- Certain medicines (e.g., long-term corticosteroids; always seek medical advice before altering any medicine)
Testing
Depending on your circumstances, your doctor may consider:
- Fasting glucose and HbA1c
- Fasting insulin (to help assess insulin demand)
- Lipid profile (triglycerides, HDL, LDL)
- Blood pressure and waist circumference
- In some cases, calculation of HOMA-IR (Homeostatic Model Assessment of Insulin Resistance) using fasting glucose and insulin.
What Can Help
Nutrition. Emphasise minimally processed foods; reduce refined carbohydrates and added sugars to lower insulin demand. Many people do well with moderate whole-food carbohydrates spread across the day. Individual plans should consider health history, preferences and cultural context.
Protein and healthy fats. Adequate protein supports satiety and muscle preservation. Dietary fats from foods such as olive oil, nuts, seeds and fish can help with fullness.
Physical activity. Regular movement — particularly resistance training — supports insulin sensitivity. Even single sessions can have short-term benefits.
Sleep and stress. Prioritising sleep and stress-management strategies can support metabolic health.
Behavioural support. Structured programmes, education and regular follow-up improve adherence and outcomes.
When Medicines Are Considered
Some people benefit from prescription medicines as part of a comprehensive plan when lifestyle measures alone are insufficient. Any decision about medicines is made by the treating doctor after a clinical assessment, considering indications, risks and alternatives. We do not advertise or promote specific prescription products to the public.

- Co-design an individual plan covering nutrition, physical activity, sleep and behavioural strategies
- Consider prescription medicines only when clinically appropriate after assessment, and discuss risks, benefits and alternatives
- Provide regular follow-up to monitor progress and adjust your plan
Frequently Asked Questions
How do I know if I have insulin resistance?
Some people notice weight gain around the middle, increased hunger or energy dips after meals. Your doctor can assess with history, examination and selected blood tests.
Can insulin resistance improve?
Often, yes. Many people see improvements with sustained lifestyle measures. Where appropriate, a doctor may consider prescription medicines as part of a broader plan. Individual responses vary.
Will insulin resistance always lead to diabetes?
No. Many people do not develop diabetes, particularly when risk factors are addressed early.
Do I need to cut out all carbs?
Usually not. The focus is on food quality and minimising sharp blood sugar rises. The right approach is individual.
How long does improvement take?
Some changes can be noticed within weeks, but meaningful, sustained improvements typically occur over months with consistent strategies. Regular review helps tailor your plan.
